| 简介 |
FIELD : chemistry.
SUBSTANCE : compositions UZM-8 are obtained using either only one or greater number of organo-substituted ammonium cations and probably alkali and/or alkali-earth cation as structuring agents. Compositions UZM-8 are described with empiric formula Mm n+Rf p+Al1-xExSiyOz and have unique pattern of x-rays diffraction. UZM-8HS represent UZM-8 zeolites derivatives and have lower content of aluminium. UZM-8HS are obtained from UZM-8 by means of acid extraction or processing with hexafluorosilicate.
EFFECT : thermal stability of obtained products and possibility of use in different processes of hydrocarbon conversion.
